Once you're on a challenge page, you can change the path portion of the URL from "pc" to "pcc" to get to the solution. eg: http://www.pythonchallenge.com/pc/def/peak.html (the problem) http://www.pythonchallenge.com/pcc/def/peak.html (link to the solution) ^

...actually, it looks like you have to solve the challenge first. I just tried this for problem 6, which I haven't solved yet, and it took me to the solution for problem 5, which I have.

You need to get the headers with: sudo apt-get install python3-dev

You'll need those to install (at least), Pillow.

Switch to the PyChallenge virtualenv. I have a bash function named 'virtpyc' that'll make that switch.

Once you've changed virtualenv, be sure to run scripts with "python", not my normal "py" alias, which points to /usr/bin/python3, and which won't have any of the following additional modules installed.

So far, I've installed: - PyPNG - Pillow
